{"certifications":[],"method":"Reconciles the seller's public receipts against Base, attests a declared same-host sample, runs the Fair Offer check (the unpaid 402, the block against the 0.2 schema, the sample, receipts and ledger URLs, the Bazaar listing), and compares the block across two unpaid requests. Pass: a complete x402 offer, a valid block that doesn't change between requests, and no rule contradicted. Failure-is-free, signed receipts and data-not-instructions can only be checked by paying the seller: when the paid probe is on and the price is at or under its cap, this run pays the offer once (and once more on a call made to fail), publishes the signed probe at paid_probe.url, and reads it; otherwise, or when the probe is inconclusive, those rules stay declared.","lost":"https://api.agoranome.com/v1/fair-offer/certifications/lost","note":"Every run is published, pass or fail.
